Each art piece is formed by hand from raw clay. It is painted by hand, then fired in an outdoor kiln to 2000 degrees F. Red hot, it is plunged into a pit with mesquite shavings igniting a blaze. The flames licking your magnet give it unique flashes of colors, making it one of a kind. Made by artist Jeremy Diller, Raku Potteryworks in the USA. Each measures 3" and comes in its own box ready for gift giving.
